Here, we develop a theory of the relationship between the reviewer's effort and bias in peer review. From this theory, it follows that journal editors might employ biased reviewers because they shirk less. This creates an incentive for the editor to use monitoring mechanisms (e.g., associate editors supervising the peer review process) that mitigate the resulting bias in the reviewers' recommendations. The supervision of associate editors could encourage journal editors to employ more extreme reviewers. This theory helps to explain the presence of bias in peer review. To mitigate shirking by a reviewer, the journal editor may assign biased referees to generate information about the manuscript's quality and subject the reviewer's recommendations to supervision by a more aligned associate editor.
IntroductionPeer review of articles that appear in academic journals is required by the scientific community, and articles are supposed to be selected for publication on the basis of merit and appropriateness alone. In some journals, after the manuscript has been received and deemed appropriate with respect to submission criteria, the journal editor assigns the manuscript to an associate editor. In such a case, the associate editor is usually responsible for the management of the peer review of manuscripts by members of the relevant research field. In other cases, academic journals are run by only one editor (unassisted, or with a managing editor who does not make editorial decisions). In some scholarly journals, rather than a single editor with several associate editors, multiple independent editors operate the journal, or there are editorial boards that decide about submissions. Nevertheless, the quality level of the journal is increased by assuring the selection of appropriate referees to identify high-quality articles and by efficiently managing the peer review process, (Burnham, 1990;Campanario, 1998aCampanario, , 1998b.Reviewers are identified through peer contact or references listed at the end of the manuscript. At some academic journals, authors are invited to nominate a minimum number of reviewers. Occasionally this is required by the submission system. Then, the associate editor will determine the disposition of the manuscript, based on the remarks of the reviewers, and his own assessment of the manuscript. The decision for a major or minor revision will be conveyed to the author by the associate editor. In general, novelty, quality of technical content, and appropriateness for publication are the criteria for the manuscript to be accepted. The goal of the peer review process is to seek fundamental knowledge and identify the most promising research. In many ideal depictions, peer review processes are understood as providing a "system of institutionalized vigilance in the self-regulation of knowledge communities" (Merton, 1973, p. 339), and thus "peer expertise is coordinated to vet the quality and feasibility of submitted work" (Lee, Sugimoto, Zhang, & Cronin, 2013, p. 3).
